Quick Shipment and communication.
January 18, 2019
: Rodolfo Feliciano from Bloomington, MN United States
I bought this to assist a friend in his first build ever. Another buddy had purchased the same unit from MAS and it rocks. So I expect this one to rock too! They shipped quickly and kept me abreast of the progress of the build!

Great online shopping

: Jason Hunsberger from Elwood, IN United States
Was looking for 300 blkout bbl and was at several sites. Out of the many sites I visited, mas defense had the best selection and price range. I will definitely come back if I want/need something else. Two thumbs up. :)

Wonderful
October 16, 2017
: Larietha C
My 39 year old son has been on me about getting this for him for his birthd as a joke. Well I decided that I was going to do it for him and surprise him so he would have it for his birthd. I had him call and find out what parts he needed and what it would look like. The customer service was awesome they explained to him what he wanted and pointed him in the right direction. After the phone call he wrote everything down that he was going to order. The guys there at Mas Defense said that it was going to be shipped Frid and it was arrived at the house at 8 am on Mond. My son came over and I surprised him early. He is so happy with the quality and the product. HE SAID HE WILL BE DOING BUSINESS WITH MAS DEFENSE FROM NOW ON. You have to understand for my son to say that this was awesome and quailty it has to pass a lot with him being in law enforcement and having several friends that build AR 15. So great job!!! If you are reading this thinking about buying one. DO IT!!!
